TO ALL WHOM I'l MAY CONCERN Be it known that I, ALEXANDER GOODHART, of Newville Post OBice, in the county of Cumberland, und State of Pennsylvania, have invented a. new and improved for Cutting and Grinding CornfFodder; and I do' hereby declare thei'ollowing to be a full, clear, and exact .description of the Asamereferencci being had to the accompanying drawings, lforming part of this specification, and in which- Figure l'is aA vertical sectional elevation througlrthe centre of my machine, the feeding apparatus beingremoved.

Figure 2- is e perspective view of my machine showing the feeding apparatus and the dischargingport.

Similar letters of reference indicate corresponding parts in the two gures.

AA represent the walls of a hollow cylinder, in shape the frstum of a cone, resting' upon the supports B B D, and having stout teeth, c c c e, projecting 'inward from its interior surface. DD represent a drum enclosed within the walls A'A, of a shape corresponding to that of tle chamber of the cylinderA A, supported by and revolving upon the upright shaft dd, and having teeth, t-t tt, projecting `outward to match the teeth of the walls A A.V The teeth of the cylinder and drum are of the same length, and overlap each other so as to grind whatever substance may be forced between them. The upper part of the drum D D is cut away, and in its place are seen the cutters E E, firmly attached to the drum aboveand below by their extremities so that they revolve directly in front of the, feed-hole F. The upper endfof the fshaft d d is provided with'a cog-wheel, G, which gears into another wheel, H, upon a shaft to which the power isapplied attire drum vJ. K is the dischargeport. M is the feeding apparatus, composedof the inclined table 111 the corrugated o r fluted roller n, to which power is appiied'et the drum o, the smooth rollerp'held in position' and regulated hy the rods U attached to the springs T T. S is a leg, which serves to support the table m. The whole feeding apparatus is attachedto the cylinder A A at the feed-hole-F by tenons projecting from the table m and' resting on the cylinder at the bottom ofthe aperture F, and still further by means of the rodsu u, of which one end is attached to the table m, and the other hooks into an eye on the cylinder. l

When the construction of my machine is thus described a few words will sufiice to explain its operation: Themachine is set in motiouby powerapplied at the druurd, and communicated tothe drum o by a band.` The f dder is fed to the rollers n and p from the table rn, and by them is forced into the cylinder A through feedhole F, `and against the revolviiig cutters E E by which it is cut into tine pieces. It then falls among the teeth ofi the drum' and cylinder, and is ground, after which it escapes through the discharge-port K.`

Having thus described my invention, what I claim as 'newgaud desire teasecure by Letters Patent, is

The combination and arrangement of the 'cutters E E and teeth Zllupcn the 'vertical drum D working in an upright cylinder,l A, providedwith teeth c c, substantially and for the purpose specified. i

To the'abov'e specification of my improvement I have signed my hand this 1st day of April, 1867.

ALEX. GOODHART.
